Reconciling the liberal tradition in normative economics with the findings of behavioural economics: on J.S. Mill, libertarian paternalism and Robert Sugden’s The Community of Advantage

Abstract

ABSTRACT In The Community of Advantage, Robert Sugden reconstructs and defends an account of the liberal tradition (LT) in normative economics in the light of the findings of Behavioural Economics (BE). In this paper, the LT in neo-classical welfare economics which has roots in J.S. Mill’s thought is contrasted with Sugden’s account. Cass Sunstein and Richard Thaler’s Libertarian Paternalism (LP) arguably attempts to reconcile the LT in neo-classical welfare economics with the findings of BE and to provide it with a Millian pedigree. To the extent that it attempts this, LP is unsuccessful. While Sugden abandons core elements of traditional normative economics – notably the ‘view from nowhere’, welfarism and the preference satisfaction view of welfare – which have a Millian pedigree and advances a contractarian alternative, he successfully reconciles his reconstruction of the LT with the findings of BE and also provides it with a sound Millian pedigree.
